我要开发一个Android应用程序，需要在2.2设备上运行;我使用HoloEverywhereLib与该用户界面是pretty的好。 我需要使用一个datepicker;如果我使用的默认组件，它有一个非常难看的样子：

I have to develop an Android app that needs to be run on 2.2 devices; i'm using HoloEverywhereLib with which the UI is pretty good. I need to use a DatePicker; if i use the default component, it has a really ugly look:

我想有像新一：

有没有办法做到这一点？

Is there a way to do it?

推荐答案

得到冰淇淋三明治风格的日期选择器的最简单方法是使用的 ActionBarSherlock库。

The easiest way to get the ice cream sandwich styled date picker is by using the ActionBarSherlock library.

然后创建对话框类：

public class DatePickerFragment extends SherlockDialogFragment implements android.app.DatePickerDialog.OnDateSetListener {

    private OnFragmentClickListener mListener;

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        try {
            mListener = (OnFragmentClickListener) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString() + " must implement listeners!");
        }
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        // Create a new instance of DatePickerDialog and return it
        return new DatePickerDialog(getActivity(), this, year, month, day);
    }

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        // Do something with the date chosen by the user
        Calendar c = Calendar.getInstance();
        c.set(Calendar.YEAR, year);
        c.set(Calendar.MONTH, monthOfYear);
        c.set(Calendar.DAY_OF_MONTH, dayOfMonth);

        mListener.onFragmentClick(DialogDemonstrationActivity.DATE_PICKER_ACTION, c);
    }
}

活动监听器类：

The activity listener class:

public interface OnFragmentClickListener {
    public void onFragmentClick(int action, Object object);
}

该对话框可以与你的活动下启动：

The dialog can be launched with following from your activity:

FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
                // Create and show the dialog.
                DatePickerFragment newFragment = new DatePickerFragment();
                newFragment.show(ft, null);

您的活动则必须实现监听，你是启动和运行。

Your activity then have to implement the listener and you are up and running.
